Summary
Cevimeline is a muscarinic agonist while cyclobenzaprine has significant antimuscarinic activity, so the two may oppose each other. Cevimeline's effect on salivation may be reduced, and cyclobenzaprine's anticholinergic dry mouth may worsen the symptoms being treated.
What this interaction means in plain words
Cevimeline and Cyclobenzaprine can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Cevimeline belongs to Miscellaneous; Cyclobenzaprine belongs to Musculoskeletal.
Why it happens
Pharmacodynamic antagonism at muscarinic receptors.
What to do
Monitor for reduced response to cevimeline, such as persistent dry mouth. Consider an alternative muscle relaxant with less anticholinergic activity if efficacy is lost.
